In Europe. I have been looking at yogurts and in all labels I see every regular yogurt with usually 3.5-4.9g of protein per 100g while the greek yogurt typically has from 3.3-3.9g.
Then I look online (probably US sources) and it’s the opposite.
What is happening here? And why is there a massive diff in protein between 2 plain yogurts (3.5g vs 4.7g)?
I’m from EU as well, Greek yoghurts usually have around 8-10g of protein.
Can you tell us what yoghurts you’re comparing? Often “Greek-style yoghurt” or “Greek-recipe” (or other similar names, depending on the country you are in) is sold, which has little in common with real Greek yoghurt.
Greek yoghurt is made from twice the amount of milk (compared to traditional/normal yoghurt), which is then centrifuged for longer. Greek yoghurt thus contains double the amount of protein, purely from milk as the basic ingredient. You should look for a Greek yoghurt that contains only milk and yoghurt cultures.
EDIT: It seems there is no regulation in EU regarding Greek yoghurt, you may want to look into your country’s regulations. Otherwise there’s no better advice then to read the labels.
The US has “greek yogurt” and “low fat greek yogurt”.
The former is what you’re looking at, which has tons of extra fat, and has more of the whey removed. The whey is the protein, so yeah.
Most US greek yogurt is the low-fat side, which brings the ratios back around.
Yeah, I’m from Europe and some brands greek yogurt has like 3g of protein and some have 10g. You might have to do some digging around. If that doesn’t help, then try getting some skyr. It’s also a yogurt and can have even more than 10g of protein.
And as for why there is a difference - just different process. They use different milk, they process it differently, they use different bacteria cultures and so on. The ones with less protein usually have more fat and are smoother while the ones with more protein tend to be a bit firmer and have a stronger yogurt taste.
